“Turning to the claim language, limitation vii recites “reconfiguring each remote radio unit by: determining a load percentage for each remote radio unit.” Claim 1 simply does not specify how to determine the load percentage for each remote radio unit and “load percentage” is a broad term. Stated differently, claim 1 does not specify the numerator or denominator to be used in determining the load percentage, but the parties agree that the numerator is the amount of load used in an RRU, as indicated above. On this preliminary record, Petitioner’s interpretation of “available capacity” as including “a single radio, a group of radios or the entire DAS system, [able to] be determined using throughput, number of connections, number of users, number of carriers, or power,” is sufficient for purposes of institution. See Pet. Reply 3 (citing Ex. 1005, 4:24–27; 5:13–15; 6:1–4; Ex. 1003 ¶¶ 104–06). On this preliminary record, as Petitioner argues (Pet.

“Contrary to these arguments, claim 9 does not recite or require a “stacked die hybrid,” “buffer cells,” any improvements in FPGA reconfiguration times, or a “3D IC.” Claim 9 recites a “reconfigurable computer system” in the preamble, but it does not even recite how the “memory” and “processor” functionally or structurally relate to the “first and second integrated circuit die elements” of the “processor module.” As indicated above, Alexander carries a presumption of enablement as a prior art reference.

“tunable compensators is a contingent argument, applicable only if one reads claim 13 to require a certain transmission rate. PO Resp. 21–25. We do not read Petitioner’s argument as so constrained. Rather, we understand Petitioner to argue that a desire for higher transmission speeds would drive skilled artisans to use solutions such as Nishimoto’s tunable compensators, particularly in light of Nishimoto’s guidance regarding the ability to achieve high speeds with the system. See Pet. 21–23. In that regard, we agree with Petitioner that the increase in transmission rates from Yamamoto’s to Nishimoto’s disclosures would have given skilled artisans reason to consider Nishimoto’s teachings. Pet. Reply 16–18 (citing Ex. 1005 8:9–11; Ex. 1007, 12:37–39). As Petitioner points out, Nishimoto specifically discloses that higher-speed transmissions were more sensitive to dispersion. Pet. Reply 17 n.9. Thus, we find the desire for higher transmission speeds and the need for techniques such as taught by Nishimoto would have given skilled artisans reasons to combine Nishimoto’s disclosure regarding dispersion compensation with Yamamoto’s system to achieve Yamamoto’s goals regarding the dispersion maps for multiple channels. Further, Petitioner does not rest entirely on the desire for high-speed operation. Petitioner argues also that using Nishimoto’s adjustable compensators and feedback control would “yield an improved WDM system capable of automatic compensation for degradation of the optical signal waveform caused by both wavelength dispersion and polarization mode dispersion of the optical transmission path, resulting in further reduced size and cost.” Pet. 16 (citing Ex. 1003 ¶¶ 99, 101; Ex. 1007, 3:41–60, 4:3–58, Figs. 17, 20, 21), 29–30 (quoting Ex. 1007, Abstract, 3:37–40, 6:56–64, 7:53–56, 11:41–46, 17:53–55, 17:59–60; citing Ex. 1003 ¶¶ 114–115); accord id. at 14 (quoting Ex. 1007, 3:19–25). Patent Owner recognizes that basis for the combination but argues that the record lacks evidence to support Petitioner’s claim of reduced size and cost. PO Resp. 25–26. Patent Owner does not contest that the modification would give Yamamoto’s system the ability to automatically compensate for signal degradation from dispersion. Nishimoto discloses that as transmission speeds increase, “changes in wavelength dispersion characteristics due to temperature changes of optical fiber; and the influence by polarization mode dispersion” both “can not be neglected,” therefore requiring a system for automatically compensating for wavelength dispersion and polarization mode dispersion,” as taught by Nishimoto. Ex. 1007, 1:34–41. We find that a skilled artisan would have had reason to make the combination because the system would gain capability for automatic compensation. Regarding reduced size and cost resulting from the combination, Patent Owner does not provide any contrary evidence and we conclude that Nishimoto’s statements regarding the benefit of its invention also would have motivated skilled artisans to make the combination.

“Although Petitioner contends “a POSITA would have been motivated to provide greater protection for the decimal integer portion (an error in which would be magnified versus an error in the decimal fraction portion)” in Padovani (Pet. 33), Petitioner does not identify any passage or combination of passages in Padovani that teaches or suggests providing, or even the need to provide, greater protection for one decimal portion than the other decimal portion, let alone by using “different coding schemes for the different parts.” Id. As Patent Owner asserts, “Padovani discloses using a single code to encode the DRC message[,]” and “does not teach using multiple codes to encode different portions of the DRC message.” Prelim. Resp. 14 (citing Ex. 1009, 45:20–22 (emphasis added)). We recognize that Petitioner’s Declarant, Dr. Min, testifies that, “by virtue of Padovani contemplating the use of an (n,k) coding scheme,” the POSITA “would have naturally sought out similar coding schemes [as those of Gils] to protect DRC messages.” See Pet. 41 (citing Ex. 1017 ¶ 156). Dr. Min further testifies that “a POSITA would have been motivated to provide greater protection for certain bits by selecting appropriate code words generated by one or more of the coding schemes contemplated by Gils,” and thus, use “different coding schemes for the different parts.” Ex. 1017 ¶ 132. Dr. Min’s testimony, however, does not address adequately why one of ordinary skill in the art would have used together different coding schemes from Gils, let alone a separate scheme for certain bits over the other bits. As Dr. Min testifies, “a single UEP coding scheme could also be used depending upon how a POSITA would have wanted to implement unequal error protection.” Ex. 1017 ¶ 132; see Pet. 33 (citing Ex. 1017 ¶ 132). As such, Dr. Min acknowledges that a single unequal error protection coding scheme could be used as well as applying different coding schemes to different parts of a message. Here, Dr. Min’s testimony that a single unequal error protection coding scheme could be used further undermines Petitioner’s position that one of ordinary skill in the art would have used the different coding schemes for different parts as set forth in Gils. Thus, Dr. Min’s testimony does not adequately explain why one of ordinary skill in the art would have applied different coding schemes from Gils to the DRC message of Padovani, much less in the manner proposed by Petitioner, of providing greater protection for the decimal integer portion than the decimal fraction portion, especially when Padovani discloses “using a single code to encode the DRC message.” See Prelim. Resp. 14 (citing Ex. 1009, 45:20–22).” slip op. at 14

“Here, for these reasons discussed above, we conclude that Petitioner has not provided sufficient evidence from prior art references or Dr. Min’s declaration testimony to support its contention that one of ordinary skill in the art would have used Gils’s techniques to encode Padovani’s DRC message in the manner required by the claims—such that the most significant bit of the plurality of bits is encoded to be less susceptible to errors. Petitioner also has not demonstrated articulated reasoning with rational underpinning to support the legal conclusion of obviousness. See PAR Pharm., Inc. v. TWI Pharm., Inc., 773 F.3d 1186, 1193 (Fed. Cir. 2014). Instead, we conclude that Petitioner used improper hindsight to reconstruct the claimed subject matter by using the claims as a guide to combine the prior art references. Grain Processing Corp. v. Am. Maize- Prods. Co., 840 F.2d 902, 907 (Fed. Cir. 1988) (“Care must be taken to avoid hindsight reconstruction by using ‘the patent in suit as a guide through the maze of prior art references, combining the right references in the right way so as to achieve the result of the claims in suit.’” (citation omitted)).” slip op. at 16

“Moreover, Dr. Min’s contention that “[t]he nature of binary numbers (or other base-x number systems) means that the leftmost bit of any binary number is the most significant bit” (Ex. 1017 ¶ 154) is conclusory. As Patent Owner points out, “Dr Min’s declaration, however, merely repeats the allegations of the Petition without any explanation or citation to any supporting or corroborating evidence.” Prelim. Resp. 20 (citing Ex. 1017 ¶ 154). That is, “[t]here is no proffered evidence that it was well understood by a POSITA at the time that the leftmost bit in binary numbers, and specifically in the DRC message of Padovani, is the ‘most significant bit.’” Prelim. Resp. 20. For that reason, we give little weight to Dr. Min’s uncorroborated testimony that “the leftmost bit of any binary number is the most significant bit.” 37 C.F.R. § 42.65(a) (“Expert testimony that does not disclose the underlying facts or data on which the opinion is based is entitled to little or no weight.”); In re Acad. of Sci. Tech Ctr., 367 F.3d 1359, 1368 (Fed. Cir. 2004) (“[T]he Board is entitled to weigh the declarations and conclude that the lack of factual corroboration warrants discounting the opinions expressed in the declarations[.]”).” slip op. at 15
